Embodiment Construction

[0036] Now take the domestic sewage treatment of a certain city as an example, and its daily sewage discharge volume is 30000m 3 , the sludge mass concentration of the mixed liquid in the raw sewage is 3300mg / L, and the concentration of activated sludge in the actual effluent is 3890mg / L, which is used as the initial value for the simulation experiment. The realization of this embodiment comprises three steps:

[0037] 1. The present invention is based on the rules of annealing cellular automata. Firstly, the corresponding initial model in the activated sludge system should be established, and the cellular state should be initialized.

[0038] A 100×100 two-dimensional space is used as the initial model. Since the traditional activated sludge system continuously feeds water and the water quality is stable, that is, the organic matter concentration and return sludge concentration remain unchanged each time, and the evolution process of each vertical section is the same, so a t...

Abstract

The invention discloses an annealing cellular automata method for simulating a process of activated sludge absorption and stabilization, which belongs to the intelligence science and environmental engineering discipline field. The invention relates to a biochemical reaction process for utilizing an annealing cellular automata rule to stimulate sludge absorption and stabilization in an aeration tank of an activated sludge system. The method bases on an artificial life system, establishes a corresponding model in the activated sludge system, designs an evolutional rule by the annealing cellular automata rule, and performs evolutional realization; the method better stimulates the condition that microorganisms absorb and decompose organic matters, and well simulates a logarithmic phase, a resting stage and a decline phase of an activated sludge growth pattern curve, wherein, the activated sludge growth pattern curve is basically consistent with a theoretic activated sludge growth pattern curve, and the final result has small difference with the actual sludge concentration. The method has guiding function for people to further know and understand the process of biological sewage treatment; and a more accurate model can be established when the method is analyzed and utilized.

Description

technical field [0001] The invention relates to the simulation of the biochemical reaction process of activated sludge adsorption and stabilization in the aeration tank, especially the establishment and simulation of a two-dimensional model of the biochemical reaction of sludge adsorption and stabilization in the aeration tank of the activated sludge system based on the annealing cellular automata rule Realization belongs to the field of intelligent science and environmental engineering. Background technique [0002] Activated sludge wastewater treatment uses artificial aeration to make the activated sludge evenly dispersed and suspended in the aeration tank, and fully contact with the sewage. Under the condition of dissolved oxygen, a large number of bacteria, fungi, algae, Protozoa and metazoans use organic matter in sewage as food for metabolism and reproduction, so as to achieve the purpose of removing organic matter. During this process, complex biochemical reactions o...
